i have a 95 ex accord 5 speed i wanna cut my catalytic converter off and run str8 2.5 exhaust to a muffler
and i wanted to know the pros and cons of doing this some say i wont pass emission but in NY they are getting rid of that test and only doing safety inspection

 

Are you turbo or something? If you go straight pipe, it'll be loud as f*ck. Why not a Hi-Flow or at least a test pipe?

 

i would just get a hi-flow cat, will pass checks and will sound just about the same

 

x2 on the high flow cat and resonator. IIRC most tech/safety inspections you are required to pass an exhaust inspection. It's not an emissions test. It's checking for leaks or non compliant exhaust systems. i.e. one without a cat or street legal muffler woudl probably fail. Best to find out what is going to be required of your vehicle to pass your state tech/safety inspection before you go hacking. Also check to see if your city/town/state has a noise (db) bylaw/law. Getting rid of the cat and resonator and running straight 2.5" to a muffler may be too loud.

 

pros- very little gain in hp. even with turbo. cons - smell, sound, attracting wrong attention(police.) .. high flow cat resonated . i have a vw that has a catless downpipe with resonated muffler and is somewhat loud but it has a turbo which helps. in a naturally aspirated car, it will be louder.

 

if you get rid of it, at least run a decent muffler, if it's not too loud and looks decent, they probably won't pay attention, you can always stick a round resonator in the middle, put a heatshield over it and it will look like a cat, I don't have one on the hatch but of course it's 25 years old, all the nightmare emissions system on the carb and the factory carb wasn't fixable anymore anyway. I wonder in states that have emissions for a car this old, if the repair parts are no longer made, you get an automatic waiver? Honda discontinued a lot of the feedback carb parts anyway

 

from experience... the worst part about removing the cat is the smell . the sound of the exhaust also gets a little more raspy. some people like that... most don't.

 

mine actually sounded better, i guess it's the larger engines do, the smaller honda engines have more of a tinny sound, which of course sounds ten times worse through one of those fart cans

 

right. personally i like the way mine sounds without, but not everyone does.

 

well mine is an 86 with the A20, I can't wait to get it running so I can hear what it sounds like with these S&S headers and my new carbs and cam, plus the stainless system I'm building right now, the dual outlets on the side of the rear bumper are going to sound kick ***. The old iron block Honda engines have a very unique deep sound, something about the newer dual cam engines alters the pitch of the engine.

 

ooo! i'd love to mess around with one of these. as soon as i have a spot for a third vehicle... definately going to need to see/hear a video of this thing running.
